[英].NET Core, Angular2, NancyFX - 404 changing URL in browser
当使用.NET Core静态文件为应用程序提供服务时,我无法在浏览器中更改URL。 这样做时,我得到了
404-找不到
南希错误页面。
唯一有效的URL是基本URL localhost:5000。 将URL更改为localhost:5000 / reservations给我404。不在基本URL上时按F5也将产生404。
如果使用浏览器同步URL localhost:4200,则一切正常,并且可以更改URL并按F5而不使用404。这是我在开发时正在执行的操作,而不是在使用IIS将其部署在服务器上时执行的操作。
在IIS Express中运行应用程序
ng构建(文件和index.html一起复制到wwwroot)
启动IIS Express
启动文件
public class Startup
{
public Startup(IHostingEnvironment env)
{
var builder = new ConfigurationBuilder()
.SetBasePath(env.ContentRootPath)

Configuration = builder.Build();
env.ConfigureNLog("nlog.config");

services.AddMvc();
services.InjectServices();
services.AddOptions();
services.Configure<Endpoints>(Configuration.GetSection("Endpoints"));
services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
services.AddSingleton<IConfiguration>(Configuration);

我了解服务器的静态内容处理存在一些问题,但似乎无法解决。
在.NET Core中托管Angular应用程序时,如何使用浏览器URL浏览?
更新1:
添加后:
PerformPassThrough = (context => context.Response.StatusCode == HttpStatusCode.NotFound)
404错误消息消失,但是页面现在为空白,除了控制台中的404以外,没有任何错误消息。
IMO您编写的中间件应位于app.UseDefaultFiles();之后; 和app.UseStaticFiles(); 而且,您仅在处理API请求。 尝试稍微重写一下它,以同时处理404错误和不处理带有扩展名的请求:
app.Use(async (context, next) =>
{
await next();
if (context.Response.StatusCode == 404
&& !Path.HasExtension(context.Request.Path.Value)
&& !context.Request.Path.Value.StartsWith("/api/"))
{
context.Request.Path = "/index.html";
await next();
}
});
您需要删除第一次await next();
。 那是在将URL重写为index.html
之前,将请求发送到/reservations
管道。
当它到达Nancy时,它会查看它是否可以处理/reservations
(它不能处理)并呈现404页面。
启动文件
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
//For serving index.html on baseurl - this can we done in AppNancyModule aswell: Get("/", _ => View["index"]);
app.UseDefaultFiles();
app.UseStaticFiles();
loggerFactory.AddNLog();
app.AddNLogWeb();
app.UseOwin(x => x.UseNancy(new NancyOptions
{
Bootstrapper = new Bootstrapper(app, env)
}));
}
AppNancyModule
public class AppNancyModule : NancyModule
{
public AppNancyModule()
{
//Get("/", _ => View["index"]);
Get(@"^(.*)$", _ => View["index"]);
}
}
Bootstrapper.cs
public class AppRootPathProvider : IRootPathProvider
{
private readonly IHostingEnvironment _environment;
public AppRootPathProvider(IHostingEnvironment environment)
{
_environment = environment;
}
public string GetRootPath()
{
return _environment.WebRootPath;
}
}
public class Bootstrapper : DefaultNancyBootstrapper
{
readonly IApplicationBuilder _app;
protected override IRootPathProvider RootPathProvider { get; }
public Bootstrapper(IApplicationBuilder app, IHostingEnvironment environment)
{
RootPathProvider = new AppRootPathProvider(environment);
_app = app;
}
protected override void ConfigureApplicationContainer(TinyIoCContainer container)
{
base.ConfigureApplicationContainer(container);
container.Register<IOptions<Endpoints>>(_app.ApplicationServices.GetService<IOptions<Endpoints>>());
container.Register<IReservationService>(_app.ApplicationServices.GetService<IReservationService>());
}
